Abstract

The invention relates to a safety fitting for blocking a line, said fitting comprising a blocking element (7, 7a) that is located in a widened section (4, 4a) of a housing (2, 2a), can be guided linearly in the direction of flow of the line and is held in an open position. Said blocking element can be moved under the influence of a pressure fluctuation in the line or moved actively into a sealing position. The housing (2, 2a) has a cylindrical sealing section (17, 17a), in which the blocking element (7, 7a) engages with a cylindrical section (15, 15a) forming a cylindrical annular gap (18).
